Reynaers Aluminium, a leading European supplier of innovative and sustainable architectural aluminium solutions, announces the release of its latest product range in façade elements in May 2009. The CW 65-EF and CW 65-EF-SG range will fit neatly into Reynaers’ existing curtain wall range, between the CW 50, CW 60 and the Reynaers CW 86 products.

With the growing concern for sustainable energy conservation and the associated awareness of man’s carbon footprint, architects and investors are evermore considering the  powerful qualities of sustainable climate control offered by the element façade. Apart from its good thermal insulation, it adds rich possibilities to the designers’ and architects’ scope of creative potential in modern building design. The new CW 65-EF addresses all of these and more.

CW 65-EF

An Element Façade creates large advantages in the construction of high rise buildings. Not only can elements be completely built in the workshop, including gaskets, glass panes, and some anchoring components. On site the assembly of the total façade is limited to mounting the completed elements in place using the pre placed anchors. Such a technique will significantly decrease the installation time of the façade. 

The new CW 65-EF provides an excellent addition to the Reynaers Curtain Wall offer, next to the CW 86-EF; this is due to its slimmer design and reduced internal and external visible width. It is set to establish itself as a system within the unitised market. It comes in a slim, yet strong profile, allowing it to accommodate a larger element size of 3700 mm high and 1600 mm wide. The appeal for Architects will be the slender design, both inside and outside, which is only 65 mm of the aluminium supporting structure, adding considerable value to its aesthetic appeal and applications. 

The CW 65 is a thermally insulated façade consisting of frames that are glazed on the outside with light glazing beads that accentuate the contour of the different volumes. The joint width of 9 mm between frames is achieved by recessed rubber gaskets. An additional insulation gasket between the glass panel and the insulation strip further contributes to its increased insulation capability with a Uf value of up to 2.6 W/m²K.  

The system allows for the integration of CW 50 opening elements with maximum dimensions of 2000 x 1600 mm (130 Kg) or 2500 x 1350 mm (180 Kg) for top hung windows and 2000 x 1500 mm (180 Kg) for parallel opening windows.  

The new system offers fabricators the benefit of reduced fabrication time and substantially simpler production methods, whilst architects will benefit from its capacity to provide increased transparency and glass thickness, allowing considerable creative freedom with a large design and functionality selection. The CW 65-EF accepts glass from 4 mm to 36mm thicknesses. 

The owner of the building gains not only the enhanced comfort provided by improved insulation, but also achieves improved safety features at a competitive price, accommodating larger building movements than previously achieved.

CW 65-EF-SG 

The CW 65-EF-SG system offers an aesthetically pleasing, yet economical structural glazing option. Although the visible width of the aluminium construction on the inside is 65 mm, the visible joint between the two glass plates on the outside is a tiny 16 mm, which is finished off with a recessed EPDM seal, creating a completely flush impression and hiding the construction frames below. In this instance the structural glass plates are glued directly onto a preassembled anodised frame, reducing the number of required components and further reducing construction time. This also guarantees excellent cohesion of glass to profiles. Working this way enables the replacement of broken glass panes to be partly undertaken in the workshop. Glass thickness can vary from 4 to 40 mm. 

 Mr. Frank Adriaenssens, Reynaers’ Chief Technology Officer, believes that this addition to their product range gives architects and fabricators considerably more creative and functional freedom: “We offer our market another sustainable solution to upgrade the architectural value of buildings, both functionally and aesthetically. The new CW 65 range is set to change the way designers and fabricators think about element façade.”
